União Biological Reserve, Biological reserve in Rio de Janeiro, Brazil.
The União Biological Reserve spans 7,756 hectares across three municipalities: Casimiro de Abreu, Macaé, and Rio das Ostras in Rio de Janeiro state.
The reserve originated from the União Farm owned by Joaquim Luiz Pereira de Souza, father of Brazilian President Washington Luis, before becoming railway company property in 1939.
Scientists conduct regular field studies in dedicated accommodations within the reserve to monitor the Atlantic Forest ecosystem and its native species.
The administrative headquarters are located at kilometer 185 of BR 101 highway, with regular bus services connecting Rio de Janeiro to Macaé through the conservation unit.
The Atlantic Forest within the reserve contains the highest plant diversity and richness among all studied remnants in Rio de Janeiro state.
